>For many of us, particularly among HN users, it's been the year of the Linux desktop for a long while.

True, "The year of the Linux Desktop" is completely subjective :P For me it was around 2014.

  Q: "What was your year of the Linux desktop?"

Now that would be an interesting statistic, more telling than some single number via collecting user-agent strings. To be clear "Your year" is when you go full Linux as your primary desktop.

Nobody uses Linux on mobile. Phone users use Android. Android uses Linux. Phone users do not use Linux.
